Abstract (en)
[origin: CN109211338A] A method used for determining a fluid quantity relating to a fluid and/or a fluid flow through a measuring device is disclosed. The method includes excitation of a total wave, which is conducted through a wall of the measuring tube, by the first and/or second oscillation transducers, by wave components; excitation of compression oscillation of the fluid by the total wave; and recording of measurement data related to the compression oscillation generated by other corresponding oscillation transducers. The invention also discloses a measurement device used for determining a fluid quantity relating to a fluid and/or a fluid flow. The device includes a controller, a measuring tube receiving the fluid and/or fluid flow passing through the measuring tube; and the first and/or second oscillationtransducers arranged on the measuring tube in an equally spaced manner. The controller is configured to drive the first and/or second oscillation transducers s as to excite the total wave through thewave components.
